Filed: 1991-12-03
Abstract: PURPOSE:To obtain a method by which infrared spectroscopic measurements can be sensitively performed on a low-concentration solution without requiring much time and labor even when the amount of the solution is small. CONSTITUTION:Two capillaries and KBr powder are prepared and one end sections of the capillaries are filled up with the KBr powder. After introducing a sample solution into one capillary, the sample solution is dried by blowing air with a drier, etc., from the end section filled up with the KBr powder. After the capillary into which the sample is introduced and the other capillary into which no sample is introduced are set on a sample table, microscopic infrared spectroscopic measurements are performed by irradiating the KBr powder on the end face of the processed capillary with infrared rays by using a Fourier transformation infrared spectroscope. Similar measurements are also performed on the KBr powder on the end face of the non-processed capillary and the ratio between the two spectra is found.
